When it was still running, the speedometer would zero out, and the car would chug until it lost all power. After sitting for a while, it would start and run for a short time. The computer returned no codes what-so-ever. So, I checked the ignition, and found no spark. I replaced the module and coils, and have good spark. Car ran for 3 miles and gave a repeat performance. Towed it home, and checked fuel pressure; 43 psi before the regulator, and 9-13 after. The cylinders are returning 150+ psi compression. As the computer was unresponsive, I bought a replacement. The only thing out of the ordinary is the cooling fan kicks on as soon as the key is turned on without the engine starting. I traced the lines to find the relay. I was expecting to find some "creative" splicing that was feeding power into a data line, but nope. Any suggestions?
